Aconitum Nappellus Seeds

Aconitum napellus Seeds – Irish Plants Direct

 

Aconitum napellus, commonly known as Monkshood or Wolfsbane, is a striking perennial producing tall spires of hooded blue violet flowers.

 

The blooms are dramatic and long-lasting, adding bold colour and architectural presence to borders and cottage gardens.

 

Foliage is deeply cut and attractive, forming a handsome clump that provides texture even when not in flower. Aconitum is highly ornamental but must be handled with care, as all parts of the plant are toxic if ingested.

 

Perfect for sunny or partially shaded beds and borders. The plants are upright and free flowering, with blooms that continue steadily through summer.

 

Excellent for pollinator friendly planting, attracting bees while providing strong vertical accents in mixed displays.

Sowing instructions

Sow thinly onto moist compost and cover lightly with fine compost. Keep cool and evenly moist until germination.

Grow and maintenance

Plant in full sun or partial shade in fertile, moist soil. Water regularly during dry spells to support growth. Deadhead spent blooms to prolong flowering or leave seed heads for autumn interest. Cut back in late autumn or early spring to encourage fresh growth. Handle with care and wear gloves when working with plants.

 

Uses and benefits
